To car/ZZ whom, t may concern.:

Be it known that I, FRnDnRro S. GABLE, a citizen of the United States, residing at Glen Rock, inthe county of York and State of Pennsylvania, have invented a new and useful Mechanism for Converting Motion, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to mechanism for converting rotary into reciprocating motion, and it has for its object to produce a mechanism particularly adapted to operate the cutter-bars in harvesters, which shall possess superior advantages in point of simplicity, durability, and general'efticiency.

To this end it consists in certain improvements in the construction of the same, which will be hereinafter fully described, and particularly pointed out in the claims.

In the drawings hereto annexed, Figure lis a side view. Fig. 2 is a planview. Fig. 3 is a longitudinal vertical sectional view on the line a' a: in Fig. 2, and Fig. I is a transverse vertical sectional view on the line y y in Fig. 2.

The same letters refer to the same parts in all the figures.

A in the drawings designates a suitable frame, which may be the frame of a harvester, and which is provided with bearings for the revolving axle B, carrying the transporting and operating wheels C C. It will of course be understood that this part of the invention may be` varied, and that a stationary frame may be usedhaving a revolving shaft, to which motion may be imparted in any suitable manner, my invention for converting motion being applicable to all kinds of machinery, stationary or locomotive, where such conversion of motion is desired. The shaft A carries a cogwheel or spur-wheel, D, engaging an interiorly-toothed wheel or band, E, which works eccentrically around the said spur-wheel D. Said band has a forwardly-extending rod or arm, I1, provided with a box or bearing, G, in which is journaled a crank, H, formed upon a shaft, I, bearings for which, J J, are provided upon the frame A., in front of the shaft or axle. The box G has a cap-plate, K, serving to hold the crank in its bearing. Shaft I carries a Hy or balance wheel, Il. The function of the crank-shaft I is to hold the band E in gear with the spur-wheel D and to prevent displacement of the said band, and the iiy-wheel L serves to overcome the dead-centers.

Pivoted horizontally upon the front part of the frame A is a bell-crank lever, M, to one end of which the front end of the rod or arm F is connected by a ball-and-socket joint, N. The other arin of the said bellcrank lever is to be connected by a. pitman with the machinery to be driven.

From the foregoing description, taken in connection with the drawings hereto annexed, the operation and advantages of this inventionwill be readily understood. As the shaft 0r axle revolves, it imparts,'through the'band E, a reciprocating motion to the arm F, and from the latter, through the bell-crank lever, to the machinery to be driven. The speed may be regulated by thevrelative sizes of the spur-wheel D and band E.

The construction is simple and not liable to et out of order, and the operation is effective.

I-Iaving thus fully described my invention, I claim and desire to secure by Letters Patent of the'United Statescombination, with a revolving shaft or axle carrying a spur-wheel, of an interiorly-toothed wheel engaging the said spur-wheel eccentrically, and having an extending rod or arm, to which an oscillating and reciprocating motion is thus imparted, substantially as set forth.

2. In mechanism for converting motion, the combination of a revolving shaft or axle oarrying aspur-wheel, an interiorly-toothcd wheel engaging th e said spur-wheel eccentrically, and having an extending rod or army provided with a box or bearing, a shaft journaled in front of the axle and having a crank journaled in the said bearing, and a balance-wheel mounted upon the said shaft, substantially as set forth.

3. In mechanism for converting motion, the combination of a revolving shaft or axle carrying aspur-wheel, an interiorly-toothedwheel engagingthe said spur-wheel, and hL ving a forwardly-extending arm, a crank-shaft the crank of which is journaled in a box or bearing in the said arm, and a bell-crank lever, one arm of which is connected with the front end of said arm by ajball-and-sooket joint, substantially as set forth.

4.. The herein-described device for converting motion, the same comprising a frame, an
